Serial No. 277,209.

This invention relates to improvements in an inside elevational view of the improved car wall structure showing more partlcularly cars. One object of my invention is to provide car wall structure particularly adapted for box cars, which is composed entirely of metal; which will be of relatively light weight; which will be thoroughly reinforced against stresses in all directions; and which is particularly designed to eliminate the damaging effects of weaving, warping or shimmying of the body superstructure.

Another object of my invention is to provide a car wall structure comprised chiefly of sheet metal panels, the latter preferably having integrally formed strengthening indentations or corrugations therein to prevent buckling and increase the' rigidity thereof, in combination with light, extremely strong metal posts, thelater being so formed and aranged as to permit ready attachment thereto of wood nailing strips for the usual inner sheathing.

Another object of my invention is to provide a car wall lstructure composed of sheet metal panels and metal posts, the latter being formed orrolled and so associated with the panel sheets that the vertical lap joints of the latter lie against and are secured to vertical webs of the posts to thus obtain a strong union of the parts, the panel sheets being uniformly corrugated or integrally braced be-l tween the posts.

Still another object of my invention is .to provide, in a car sheet metal wall arrangement having posts associated therewith, strong,

substantial and relatively inexpensive means for attaching the upper and lower ends of the posts to the adjacent car sills and end or side plates. 10 Other and' more specific objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming'a part of this specification, Fig. 1 is a side. elevational view of a portion of a box car side showing'my improvements incorporated therein.` In this Kiew, the car wall is shown from the end to the nearest usual side door post. Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1 upon an enlarged scale. Fig. 3 is one of the posts and means of attachment to the panels and car framing members. Fig. 4 is a' vertical sectional view corresponding to the line 4 4 of Fig. 1, Figs. 4 and 5 being upon an enlarged scale and parts being broken away to better accommodate the views on the sheet. Fig. 5 is an enlarged horizontal detail sectional .view corresponding to the line 5 5 of Fig. 1. .Figs 6, 7 and 8 are views "illustrating a modified forni of my invention, Fig. 6 being an inside elevational view, Fig. 7 a vertical sectional view on` the line 7 7 of Fig. 6, and Fig. 8 a horizontal sectional view on the line 8 8 of Fig. 6. Figs. 9, 10 and 11 are views illustrating another modification of the invention, Fig. 9A i being an inside elevational view, Fig. 10 a ver-ky tical sectional view on the line- 10-10 of Fig. 9 and Fig. 11 a horizontal sectional view on the line 11-11 ofV Fig. 9. Figs. 12, 13, 14 and 15 are. views illustrating still another modification, Fig. 12 being an inside elevation view, Fig. 13 a vertical sectional view on the line 13 13 of Fig. 12, and Figs. 14 and 15 being horizontal sectional views on the lines 14-14 and 15 15, respectively, of Fig. 13.

Referring first to the construction illustrated in Figs. l to 5, inclusive, the car side sill isuindicated at 20, the side plate at 30 and the panels are each indicated generally by the reference character 40. The posts are y designated generally by the reference character 50.

The 'side sill willgenerally bea channel having a vertically extending web or section f 21 and a horizontal inwardly extending top flange or section 22. The top side plate 30 is shown in the form of aLZ-bar having an inner vertically extending flange 31,. a horizontally extending web 4or section 32 and a depending outer flange 33. y

The sheet metal panels 40 are preferably of like construction except for minor variations that may occur on those panel sheets at the ends where united to the car corner post 70 and the side door post 71. .Each panel will preferably be of a length corresponding -to the distance between the side plate and side sill, the width of the panels being made to suit. Each panel has a lower relatively wide flat marginal portion 41 extended downwardly over the web 2l of the side sill, said marginal portions being secured to the side sill by a series of rivets 72. The panels also have top, somewhat narrower flat marginal portions 42, which lie against the inner face of the depending llange 33 of the side plate, said top marginal portions being secured to the side plateby a series of rivets 73. Intermediate the tops and bottoms of the panels, the latter are provided with a series of inwardly offset corrugations or indentations 43, each of the latter, as shown, havinga flat rectangular bottom 44, upper and lower inwardly converging walls 45-45 and inward-A ly converging end walls 46-46. The panels are thus supported, horizontally, by what approximate reverse corrugations 47 which are appreciably narrower, as shown in Fig. 4.

The adjacent vertical edges of each pair of panels have flat margins '4S-48 which are overlapped and riveted together, as indicated in Fig. 5, by a. line of rivets 74, said rivets also uniting the overlapped edges of the panels to the central web 5l of the corresponding vertical post.

The post 50 may be said to be of double U-cross section, as best indicated in Figs. 2 and 5, and in addition to the main outer central'web 51, has vertically extending webs 52 extending inwardly therefrom, at right angles. At the inner ends of the webs 52, the metal is thence extended in opposite directions to provide webs 53-53 arranged parallel to the car side, the latter in turn being bent outwardly so as to provide still Jfurther webs 54-54 arranged perpendicular to the car side and the latter terminate in flanges 55-55 which are secured by vertical lines ot rivets 7 5 7 5 to each of the inwardly oset corrugations 43 of the panels at each side of the post.

Referring to Fig. 5, it will be noted that the webs 52 are ot approximately twice the width or" the webs 54 so that the longitudinally extending webs or sections 53 are inwardly ollset from the bottoms of the corrugations a distance approximately the same as the depth oit the corrugations. lit will further be observed that a very rigid tubular construction is thus formed between each panel sheet and corresponding adjacent half of the post, this tubular construction comprising the portions 52, 53 and 54 of the post and the series of inclined end walls 46 of the corrugations. This arrangement is exceedingly strong and well adapted to resist stresses in any direction and particularly are the panel sheets braced against collapse from blows applied thereto in a horizontal plane from any direction. Vertically, the panel .65 sheets are greatly strengthened, inasmuch as Laietana the post is connected to the bottoms of the corrugations and forms a bridging piece therebetween, thus preventing the latter from yielding under any vertical stress. It will further be observed that the post provides an inwardly facing open channel adapted for the reception of a wood nailing strip, indicated by dotted linesv in Fig. 5 and referenced 76. The innerface of the latter will be flush with the sections 53 of the post and the inner sheathing applied thereto, there thus being left a proper space between the sheathing and the corrugated sheets for the usual battens on the outer side of the sheathing.

The bottoms of the posts are rigidly attached to the side sill by base or attaching plates 60. Each of the latter has a main bottom flange 6l by which the plate is secured to the flange 22 of the 'side sill by a plurality of rivets 77. Said flange 61 is extended inwardly beyond the sill flange 22 as shown in Fig. 4, so as to provide an ample toe-hold or support for the floor boards which come opposite the post. The floor boards at either side of the post of course have ample support on the flange 22 of the side sill. Said base plate 60 also has two cdmplemental vertically extending flanges 62-62, each being formed to t against the sections 52, 53 and 55 of the post, as best shown in Fig. 5. Each said flange 62 is riveted to the post by a rivet 78 and the lowermost rivet of the series7 5 is also utilized for this purpose. The flanges 62 terminate within the wood nailing strip pocket so as to leave the space for the latter clear.

rllhe upper end of each post is secured to the side plate 30 by a similar base or attaching plate 160, the only differencebeing that the latter does not have as wide a flange as the flange 61 used at the lower ends of the posts.

l/Vith the construction described, it will be seen that the posts may be made of relatively light gauge metal, while at the same time obtaining great vertical column strength, thereby preventing buckling under any ordinary conditions. `Further, the means ot attachment to the side sill and side plate are such as to practically eliminate any possibility of the post tilting out of the vertical with respect to either the side sill or side plate, either transversely of the car or in a plane lengthwise thereof, thus eliminating or minimizing the possibility of weaving or warping of the superstructure. The horizontal corrugations in the panel sheets obviously brace not only the sheets themselves but the posts, one with another, and the corrugations `serve to prevent shimmying or vibrating of the panel sheets, a dilliculty heretofore experienced in certain types of box cars having sheet metal walls. The panel sheet arrangement is manifestly such that the same can be readily manufactured and the sheets assembled with the posts anda complete unit for 13 one-half of the car side readily applied to thel car side sill and side plate, it only being necessary to apply the lines of rivets 72 and 73 and the rivets which secure the plates and 160 to the side sill and side plate, thus minimizing the cost of manufacture and assenbling. f

Referring to the construction illustrated in Figs. 6, 7 and 8, the sheet metal panels 140 are the same asin the first described construction and said panel sheets are attached to the sidefsill 120 and the side plate 130 in the same manner. In this modification, the post 150 is made of singleU-cross section, as shown in Fig. 8, the same having a main Ibottom or outer web 151 secured to the over- Y lapped vertical edges of the panels by the vertical series of rivets 174. The post also has side arms 152-152 and oppositely extended inner flanges 155-155. The same open channel formation for the reception of a wood nailing strip is'provided as in the first construction. y

In this form of the invention, the posts 150 are secured at their lower ends to the side sill by a T-shaped, base plate or casting 160', the latter having a lower horizontal flange 161 and a vertically extending flange 162. The latter is secured to the flanges 155 of the post by rivets 175 and the bottom flange 160' is secured to the top flange 122 ofthe side sill by rivets 177.

The top end of each post 150 is secured t the side plate by a somewhat similar attaching plate, the same having a depending verti ical flange 163 riveted to the flanges 155 of the post, a horizontal flange 164 riveted to the web of the side plate 120, anda vertically extending flange 165 riveted to the vertical inner flange of the side plate.

. Referring next to the-construction shown in Figs. 9,10 4and 11, the arrangement Iof,

panels 240 Vand posts 250 is the same as that shown in Figs. 6, 7 and 8. The only difference is in the face of attaching plates for the posts. The base plate 260 has a horizontal bottom flange 261 riveted to the top flange 222 of the side sill. and a vertical-ly extending flange 262 which extends from end to end of the base plate as shown in Fig. 11.

The flange 262 is offset intermediate itsl ends as indicated at 263-263, where it is riveted to the flanges 255 of the post, as by rivets 275. .The upper attaching plate is similar to the lower, except that it has an additional upturned flange 264 rivetedto the inner vertical flange of the side plate 230.

Referring next to the construction illustrated in Figs. 12 to `15, the sheet-metal panels 340-340 are the same as in the first described form and said panels have their direct attachments to the side sill 320 and side plate 330 in the same manner.

The posts 350 are substantially the same as the posts 50 of the first described construction, the only substantial difference being post 350 is necked-in, the sections 352, and l 354 which extend perpendicularly tothe side Wall of the car are all of the same depth and of lesser depth than the depth of thecorruations in the panel, as clearly indicated in igs. 14 and 15, although the general contour of a cross section of the post remains the same, as will be evident.

The necked-in upper and lower ends of the post are secured tothe side sill and side plate by base or attaching plates 360, similar to t-he base plates 60, each said plate 360 having a bottom horizontal flange 361 and a vertically extending flange 362, the latter conforming throughout its length to the contour of the necked-in portion of the post. The attaching or base plate 360 is riveted tothe upper flange 322 of the side sill. By neclringin the post at the bottom thereof, it is unnecessary to extend the base flange 361 of the attaching plate.

Although I have vherein shown and described my improvements with particular reference to the side wall of a box car, nevertheless, I am aware that the improvements may be equally well employed in the end wall lstructure of a box car and also that-many features of the improvements maybe employed-with beneficial effect in wall structures of other types of cars without departure from the spirit of my invention. All changes, modifications and variations are contemplated that come within the scope of the claims appended hereto.
